Be it known that a citizen of the United States, residing at Kansas. Cit,in the county of Jackson and fi ssouri, have invented a certain new anduseful Improvement in Spring Clasps, of which the followingis a completespecification. 1

This invention relates to spring clasps and'more especially to clasps,ofthat class exemplified by Patents Nos-1,089,829 and 1,186,656, issuedand June 13, 19l6,-respectively, my'particular object being to produce amore durable and etiicient and at the same time simpler and 5 moreattractive clasp than those referred to, which can be adapted tofastening scarfs, ribbons, laces and the like, aswell as for retainingthe hair in place in a neat and attractive manner. 1 H

A further object is to produce an ornamental clasp comprising a bodyportion having tapered roll edges and apin pivotally interlocked at oneend to the body and adapted when closed against the said body, to beautomatically secured in such position by such roll edges, with locks ofhair or the ends of scarfs, lace collars and the like, clamped firmlytogether;

With these objects in view the invention consists incertain novel anduseful features of construction and combinations of parts as hereinafterdescribed and claimed; and in order that it may be fully understoodreference is to be had to the, accompanying drawing, in which:

igure 1 is a face view of a spring clasp embodying the invention.

1. A spring clasp comprising a body-portion having parallel roll edgesextending for substantially the full length of and overlapping andspaced a pin pivoted at one end to the body-porti0n; the pin and rolledges bearing a laterallyyielding and Wedge relation at their oppositeends to insure engagement and disengagement respectively, when the pinis operated pirotally under sufficient power to close or 52. In aspringclasp, a member having a bodyportien and side roll edges; saidedges being spaced at their inner sides from the body-portion and havingtapered ends to provide an interposed longitudinal slot having flaringmouths at its-ends, anda pin pivoted at one end tosaid clasp and adaptedfor engagement with the roll edges thereof.
